Preparation, epitope identification and application of a prv tk protein monoclonal antibody

Abstract

The application relates to preparation, epitope identification and application of a PRV TK protein monoclonal antibody, the amino acid sequence of the light chain variable region of the monoclonal antibody is shown as SEQ ID NO. 2, and the amino acid sequence of the amino acid sequence of the heavy chain variable region is shown as SEQ ID NO. 3. Meanwhile, the application provides a PRV TK protein antigen epitope peptide, and the specific amino acid sequence of the PRV TK protein antigen epitope peptide is shown as SEQ ID NO. 4. On the basis of successfully expressing a PRV strain TK protein, the PRV strain TK protein is purified and used as an antigen to immunize mice, and a hybridoma technology is used to prepare a specific monoclonal antibody for the PRV strain TK protein, so as to provide an important tool for TK protein structure and function research of a PRV epidemic strain, and subsequent establishment of a PRV specific diagnosis method and related research.
